To all whom it may concern: 1

Be it known thatI, GEORGE J. VVILLIAMs, a citizen of the United States, residing at 81321 Market Street, Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Combination Knockdown Tools, of which the following is a specification. v

My invention relates to new and'useful improvements in a combination knockdown tool and has for its primary object to provide a tool of this'characterwhich will combine'a level, square,rplumb rule,"str aight edge, and spirit plumb so that there are practically five tools in one. I

Another object of my invention is to so construct the tool thatthe same will be formed of a number'of sections which may be disconnected for packing and so occupy a relatively small space or connected in different ways to produce different tools.

A further object of-this invention is to provide fastenings of unique construction for the several sectionswhereby they will be firmly held in their operative positions.

WVith these ends in view, this" invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims. i 1 c i In order that those skilled in the art to which this invention appertains, may understand how'to make and use the same, I .will

describe its construction indetail, referring by numerals to the accompanying drawings forming a part of this application, 'in whiohz Fig. l is an isometric view of my combina tion knockdown tool, showing the sections connected for use as a level, straight edge, plumb rule or spirit plumb.

'Fig. 2 is a similar view showinghow the sections are connected for use as a square.

Fig. 3 is an enlarged brokenside elevation .Fig. 9is a side elevation thereof, partly in section.

Fig; 10 is a fragmentary sectional edge view of the tool, illustrating the connection or joint between twosections when inendwise'alignment. .l In carrying out. my invention as herein embodied, 2 represents the toolas a whole, consisting ofa plurality of sections which for convenience of illustration are here shown as three in number, designated by the numerals '3, 4 and 5.

fAn intermediate section: 4 comprises a substantially rectangular body,having a lug 6 at one or both ends of less size-than-the cross sectionalareaiof the body-,and in each transverse-T slot 7 Figs. 6 and 7 "for-the reception of the T rib Son the outer end of one of the lugs or projections .6 on an intermediate section. The sliding block carries a screw rod 11 which passesthrough a pair of associated spaced parallel partitions 12, with 1ts end projecting into a bore' 13 leading of these. lugs or projections is formed, a

the sliding block 9, said T rib beingjslidable fromthe recess. 10, said borebeing of s'ufii- 1 cient' length to accommodate the major portion of the screw rod 1:1; The end of the screw rod which enters the sliding block :9

is: preferably polygonal in cross section to driven into the sliding block and through the "screw rod. An adjusting nut 15 has prevent rotation of said-screw rod relative to the slidingblock, and 1n order to secure these two partstogethema pin 14 may be threaded connection. with the screw rod 11 and is positioned between the two partitions 12 and held thereby against endwise' move- Fronr this portion of :the description it will be readily notedthat whenthe sliding block9 is moved out, as shown in Fig. 4:, by revolving the adjusting nut15. in the proper direction, to which access is had through the opening 16, the Tflrib 8 maybe slipped into the T slot .7 i'na projection-6 at the end of an I intermediate section then, by reversing, the

, rotation of the adj usti-ng nut 15, the sliding b1ock9 will be drawn intothe recessi lO, pulling the projectionfi along with t intosald recess until the coacting ends of the se c tions butteach other, thus firmlyholding the two sections together.

Although after the lug 6 has been-drawninto the recess 1O --the r -e:-can-be'no movement of one section relative to the other, I desire to provide additional meansv to insure against lateral movement of one section relative to the other, and thereforetatongue=17f is provided in the inner end of each end section for-registrationwith a groove 18 at each end of an intermediate section.

One of the-end sections, as-3, is provided with a-Tgroove" 19 along one of its edges-at its outer end, so that said; groove is open in the outer end of the section 3. This provides for the other end section being-attached to the outer end-of the end section 3 Icy-sliding the -T' rib 8-onthe slidin'gblock: 9 in theend section 5 into the T groove-.191 and: then drawing the sliding blocki into the :end: section 5 until its inner end abutsi theiedgeeof the: end section 3, as plainly shown in Figs. 2',- 8 -and 9: When brought into the abutted relation the tongue 17 T on theend section 5 will enter the groove 20in the edge: oft the section Scrosswiseof- -the T groove 19, thus properly aligning the two: sections to form thesquarepart-inFig.2.

In addition-totheopenings 16in the end sections wherein are located ithe adjusting nuts, alllor some of-zsaid sections arezprovided -with other openings 2L,v wherein are locatedthe spirit glasses 22 1and as will be obvious andtherefore not explained in 7 detail, these spirit-"glasses are of ordinaryconstruction, and .someare in transverse positi ons while others: arein' longitudinalv positions withrelation to-1 the toolawhen. connected" as shown in Fig; 1.

All of: the openings 16 and2lpass entirely through the body I of the section, in which they are formed so as;to beev-isible or accessible' from either 'face or side ofthetool, and in order to protect the portion. within 1 the openings against breakage when not in use and also prevent the accumulation of dirt in said openings,.the'.:latterz may' be. closed by suitable covers AlthoughLdo-n'ot wish toibe limited to the; particular construction i-orr arrangement of" these; covers,- a' satisfactory: method of mounting such covers consists inxproviding a. frame'24 which is embedded in the-body of the section, each framenincludin i two 2?, the latter. comprising-two spacedbarsr Between the bars of" the neck is pivoted the? tail =28 and the cover; 23; thereby permittingsaid cover-to be swung into either'ofthe bezels' 2.5or; 26; it beinguhdmto'od that oneof these surrounds an open-ingJG or21, so that when;the cover, is in-onebezel, said cover will closeone end "of the opening, butk wlien swung; over; into i the other" bezel, said cover will lie flush wan the-face of tlie-tool 'so as not to interfere with the proper use of the tool; In order that the cover shall be held in either the open or closed position, a spring 29- isassociated with the tail- 28 so as to lie against either face of said tail according to the positioniof the cover.

One of the end sections, as 3, has a number of notches 30-.formedr. inits outer end into Which is laced the end of the plumb line 31, carrying the plumbbob 32, the latter being so positioned asto partially. enter theplumb bobopening33, and inorder, that the worka: spirit plumb. The'tool may alsoibe used as astraight edge in anyposition-.,, When the, plumb lineand bob. are attached, the

tool, may then be used as a. plumb, rule.

When it is desired; to use the tool: as a square, as shownin Fig; 2, one of; theend sections, as15, is;connectedt'o-v the outergend of the other endfsection. 3, soas to. project from. one edge thereof; y

Of course, I donot w-i'sh' to-be, limited to the exact details of' construotionv'herein shown: and described,.as these may be varied within the limits: of the appended claims Without departing from'the. spirit of my invention. n

Having thus fully describedmy invention, what-I claim as new and useful-is 1..A-tool comprising; an intermediatev section-eand two endsec tions, a lug at each, end

of the intermediate section, said lug having a T. shaped groove therein,- each of said; end sections having a recess 1n the 1nnerend,yan opening OIOSSWlSG tlIGIBOf and commun1cat- 'ing'with-the recessandabore-leading from saidrecess, a sliding. block mounted-in the recess, a T shaped .rib onthe blockforregistration with thergroove in a lug; on the intermediate. section, a; screw rod attached to the partitions-"acrossthe: recess, and; through which the screw rod passes, and an ad ust1ng nut having'threaded connection with the screw rod and positioned between the partitions and accessible-throughitheopening, the 1 tion and twoend sections a vlug; at each end of the-intermediate;section, said,lng having b'l ockrand movable intothe-bore, a: pair of a T shaped groove therein, each of said end sections having a recess in the inner end, an opening crosswise thereof and communicating with the recess and a bore leading from said recess, a sliding block mounted in the recess, a T shaped rib on the block for registration with the groove in a lug on the intermediate section, a screw rod attached to the block and movable into the bore, a pair of partitions across the recess and through which the screw rod passes, and an adjusting nut having threaded connection with the screw rod and positioned between the partitions and accessible through the opening, the revolving of said nut drawing the sliding block and lug intothe recess until the c0nnected sections abut, one of said end sections further having a T shaped groove in one edge running longitudinally, and open at the outer end of said end section for the reception of the rib on the block of the other end section when the tool is used as a square, and tongues 0n the inner ends of the end sections for registration with grooves in the ends of the intermediate section and a groove in the edge of one of the end sections.

In testimony whereof, I have fixed my signature.

GEORGE J. WILLIAMS.
